Just saw the film tonight - It was OK.
I'm a big fan of both Mikkelsen and Yen and really enjoyed their performances. The cgi was great and the story was solid.
My only complaints are
1) No gore. Very sad that we're never going to see people's limbs being chopped off or guts blasted through. Takes away the immersion from the fighting.
2) There were too many characters and many were left very undeveloped. Whittaker's character was a waste, in my opinion.
